I'm glad you brought this topic up. I was thinking of getting a Duramax or 6.0 for my next truck. I thought i could buy a lot of gas for the price of the 6.6. However, if the 6.0 gets the same mileage or worse than a 5.3 while towing I will lean towards the Duramax.

How does the 6.0 pull compared to the 5.3? Is there as big of difference as you anticipated?

6.0 pulls great really dont even know the trailer is back there...yeah i was told the same thing your can buy alot of gas for what the durmax costs i was thinking of getting one too but my uncle work at a dealer ship and the way it figures out that if your just a weekend puller just get the 6.0 the only way you really get your money back out of the durmax is if you pull all the time...unless money is not a problem then speend 10,000 more and get the durmax...but from what iam told the 6.0 should get better mpg hoping to see what others are getting or if theres something i can do...nose cone for the trailer or get the 300 dollar programer...??

All right, gotta ask to clarify this when comparing one vehicle to another-list the way each vehicle is equipped when comparing mileages.

Motor-Any Mods Performed
Transmission
Gear Ratio
2WD or 4WD
Chassis Rating (1500, 2500 or 3500, Dually or Single)
Cab Configuration
Box Length
Topper/Tonneau Cover
Tire Size (If Not Stock)
Lift (If Any)
Weight Towed
Any Other Factors That May Contribute To Fuel Consumption

This will help clear any confusion that may occur in mpg comparisons.

GET THE DIESEL!!! Then go right to Bully Dog and get the Power Pup Commander. My buddy gets 16 mpg pulling his 27 ft. trailer! 20 mpg without.

Quad Cab

4x4
Short Box
BFG 35's? I think.
I think his trailer weighs 7,000 lbs. Not too sure though.

I had a 2005 2500HD 6.0L 4x4 crew cab. 15mpg at 55mph on the highway. 12 at 80 on the highway. 9 towing at 65. Towed a 6x12 with 3 bikes and a fourwheeler. I sold it because I couldn't stand the gas bill. I wish they would hurry up and put a small diesel in a half ton truck. http://www.thumperta...milies/bonk.gif

Just for reference, my stock 2005 duramax 3500 srw crewcab longbed (same as a 2500hd with slightly bigger tires, etc.) -> mileage is 23+ mpg @ 50-55 mph on the highway, about 19 at 75 mph and 16 mpg towing at 60-65 mph. Towing a 6 X 10 enclosed trailer with two bikes (predominant factor is wind resistance and not weight!).

I would also go for a small diesel in a 1/2 ton truck - I need to tow 8k pounds (horses) and want the efficiency that a diesel provides.

I'm the service manager for a GM shop and the 6.0L engine in the 3/4 tons get the worst mileage of any other combo we have. If you tow and the truck do less than 12k miles a year look at the 8.1L big block. 8.1L has the good transmission and the option is not much. If you think you need more GET THE DIESEL. The difference in fuel bill alone will make the additional cost of the monthly payment. If I had a dollar for every customer that bought the 6.0L because it was a good deal and it will tow what I got, then pissed because they stop for gas so often I would be retired riding MCs in the hills.

Does the 6.0 have the cylinder cutting feature that the new 5.3 have? Dodge calls it MDS (Multi Displacement System?) I'm not sure what Chevy calls it or if the 6.0 has it. It would really be nice on the 8.1 liter. Bring it down to a 4 liter cruising down the road with no load.

Just so you know the MDS system doesn't work very well. We first got it on our Envoys and they still got poor mileage. You can hook up the tech 2 scanner and watch it drop/add cylinders. The 5.3L engine is the best power/fuel mileage combo out there. I have an 06 crew cab 1500, 5.3L without MDS, 3.23 gears, and pull a 8,500lbs toyhauler (rear susp bagged) in 3rd gear. Because of the tall final drive the truck is turning 2,500 rpms at freeway speeds. I get 8.5 to 9.5 mpg towing at 67-72 mph and over 20 mpg driving back and forth to work. My riding partner has an 03 durmax, same trailer, get 8.5 towing and 16-18 without.

I'll second on the 8.1L. The mileage on the 6.0 is terrible. The 8.1 will actually do better towing and usually is no worse unloaded.

If you want one get it now. GM in their infinite wisdom has decided to drop the 8.1 in their light trucks. It's a shame, the 8.1 is a good engine.

In respect to the duramax, it is a get engine. But for me it was not worth the additional price that all the chevy dealers around here wanted or $8,200.00 with the Allison tranny. In addition to this diesil is on average .42 cent more a gallon. I typically keep my vehicles 3-4 years before trading them in. Currently I have a '06 2500hd LT crew cab 4wd. This truck is used alot for work but never abused. I average between town and highway 14.5mpg. As far as towing, I pull a 28' v-nose enclosed sled trailer. The 6.0 is not a Duramax by any means, but in four years time with typical mileage or 22k a year it would only save me $2,300.00. Take that saved 2.3k less the $8,200.00 for the duramax and I would be in the hole $5,900.00. With this in mind, I am happy with what I bought.

05 sucked for mileage there is some tricks though buy the 01-03 lb7 pipe from the down pipe to the tail pipe (the section with the cat on 05) a cold air intake and a chip on one of the lower settings I have a customer getting 17-18 mpg out of his 05 pre mod mileage was 12.

the 06 on the other hand is awesome more power and a .66 to 1 top gear they do pretty good on mileage stock and can lay down a pretty good smoke show too:eek:

And so far the 5.3 is the only motor with Displacement On Demand.
